The latest list of the 100 highest-paid union bosses is led by employees of the MLB, NBA, and NFL players’ unions — unsurprising, given the prevalence of seven-figure contracts among the professional athletes they represent.

HALF A MILLIONAIRE: American Federation of Teachers (AFT) President Randi Weingarten was paid $543,150 last year.

However, dozens of union officers and employees — whose paychecks come from teachers, government workers and blue-collar laborers — are also paid $350,000 or more.

American Federation of Teachers (AFT) President Randi Weingarten was paid $543,150 in 2013, while National Education Association (NEA) President Dennis Van Roekel was paid $411,172.

Among construction industry unions:

Laborers’ International Union (LiUNA) President Terry O’Sullivan was paid $663,981

Boilermakers President Newton Jones was paid $491,866

United Association of Plumbers & Pipefitters (UA) President Bill Hite was paid $468,011

Sheet Metal Workers (SMWIA) President Joe Nigro was paid $460,395

United Brotherhood of Carpenters & Joiners President Doug McCarron was paid $452,974

First on the 2013 list, MLB Players Association Executive Director Michael Weiner received $3 million in total compensation. In 100th place, Air Line Pilots Association Sr. Managing Attorney Jim Johnson was paid $361,282.
